IM PROVEM ENT IN CAR-HEATERS.

Specification forming part of Letters PL tent No. 201,061, dated March 5, 1878; application filed December27, 1877.

To all whom it may concern:

Be itV known that I, WESLEY SMITH, of Adrian, in the county of Lenawee and State of Michigan, have invented new and useful Improvements in Car-Heaters, of which the following is a specification:

My invention'relates to steam-heating apparatus for cars.

My improvement consists, first, in combining, with a steam-coil and a pipe surrounding the car, an arrangement or system of valves for regulating the supply of steam, and consequently the heat, in different parts of the car, as hereinafter described.

My improvement consists, secondly, in combining, with the steam-heating pipes, a chamber beneath the car, constructed with an auto-l matic valve, adapted to open and allow the water of condensation to pass off with the Sediment when the steam-pressure is withdrawn, as hereinafter described.

My improvement consists, thirdly, in combining, with said chamber, means for relieving the chamber when steam is on, consist-ing of an inverted-U or siphon pipe provided with a valve, as hereinafter described.

In the accompanying drawings, Figure l is a plan view of the lower portion of a car Vprovided with my improved steam-heating apparatus. Fig. 2 is a side view of the car, a portion Vof the paneling being removed to exhibit the heating apparatus. Fig. 3 is a vertical transverse section of a car. Fig. 4 is a view, on a larger scale,of the chamber for the water of condensation. Fig. 5 is a perspective view of a screen for the coil and a portion of a fender for the pipe.

Like letters of reference indicate corresponding parts in the various figures.

valve being opened by a spring, b, when steam-pressure is withdrawn.

Sis a Siphon or inverted-U pipe, one arm, s, extending downwardly to near. the bottom of the chamber, the other arm, s', extending downwardly on the exterior of the chamber. The pipe S is provided, in its bent portion, with a valve, s", to regulate the discharge through the Siphon. The chamber is provided with a jacket, B".

K K are perforated fenders for inclosing and protecting the pipes C C. E E E E are valves for admitting steam to either or both sides of the car from either or both ends of the same, being located in the pipes C C, one on each side of each door. F F are valves for admitting steam to the coils A A when greater heat or more warmth is reqnired at the ends of the car, the steam passing through pipes C C to the coils. G are valves at the lower ends of the coils, to permit water of condensation to pass Vdown through pipes g g ont at 1oottom of car.

The supply-pipes H H lead from exible couplings I I, and are provided with valves H Hl to regulate the supply of steam, and jackets or casings H" H.

J J are ornamental screens for concealing the steam-coils A A, and are preferably provided with marble tops J. rlhe couplings I I are made iiexible, preferably, and are protected by a casing.

I intend to use live and dry steam, which may be taken from the boiler, preferably from the injector or pipe. The steam-pipes will be under the same pressure as the boiler, which is about one hundred and twenty-iive pounds to the square inch.

Operation: When the car is to be disconnected, the valves H H in the pipes H H are closed, so as to let the pipes cool gradually, and when the'steam has condensed within the pipes the valves b in the chambers will open automatically, owing to the pressure upon the valves being withdrawn and allowing the springs to act, thus permitting the water of condensation to pass out. If it is desired to remove water of condensation from the chamber when steam is on, the Siphon attachment is 1 ThewlyesElE fegulat the supplyfi my ji nyenti-un 1i thetions ofthe can 1 1 1 5'a`dapted11t`o: 1h81 dosed bythe steampressure,
